Maybe you just have a feedback system that doesn't feed back. Thirst merely signals that the body is low on water. I don't see why an adaptation would evolve to fool a desert dweller, and not warn him he is about to die of thirst.

One of the dangers of following any diet is becoming dogmatic, developing tunnel vision and, as a result, failing to adapt the diet to your own needs (bio-individuality). What alterations/adaptations to the Paleo diet have you made and why?
